USES OF HELIUM GAS AND LIQUID HELIUM BY INDUSTRY
From manufacturing to flight, helium is widely utilized throughout the aerospace and aircraft industry. In space flight operations, helium is used to purge hydrogen systems and works as a pressurizing agent for ground and flight fluid systems. It is also a source of lift in weather and other surveillance balloons.
Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications. It is also used in combination with argon as a source of inflation in a growing number of airbags.
In combination with oxygen, helium is used in diving to help eliminate nitrogen narcosis, reduce breathing resistance at depth, and shorten decompression stops. Known as heliox, the mixture allows divers to reach greater depths for longer periods of time. The deeper the dive, the higher the concentration of helium, allowing divers to explore more and weld longer.
Helium plays a significant role in the manufacturing of semiconductors, LCD panels, and fiber optic wire. It cools parts and components quickly to enhance throughput, controls the rate of heat transfer to improve productivity and reduce defects, and functions as a carrier gas in the production process.
Helium's inert properties at arc temperatures make it an ideal gas for welding materials with high heat conductivity such as aluminum, stainless steel, copper and magnesium alloys. Helium is also used in heat treating processes such as gas quenching and in furnace atmospheres to produce parts with higher tolerance and improved quality.
